After brewing is complete, the state of the coffee bed can reveal a lot about the extraction, and the color of the coffee liquid is also often used as a basis for judgment. Many people, upon seeing darker-colored coffee, instinctively assume it tastes stronger, or even suspect it is murky. In fact, the depth of color is related to extraction yield and roast level, but it does not directly equate to a higher or lower level of clarity. This article starts with the color of the coffee liquid, analyzes whether dark color indicates murkiness, and, using Front Street Coffee's comparative brewing examples, explains how to judge clarity through taste rather than sight, while also offering practical advice on bean selection, resting beans, parameter control, and pouring technique.

Those who chase crema often reach a fork in the road: the thicker the crema, the richer the flavor, but the delicate floral and fruity notes tend to blur along with it. Richness and clarity are like the two ends of a seesaw—finding your own balance point is more worth pondering than simply piling on more crema. The essence of crema is carbon dioxide, lipids, and proteins. [more…]

Many coffee enthusiasts notice during pour-over brewing that the coffee liquid is sometimes not as clear as expected, and may even appear somewhat murky. Does this "tea-like" cloudiness mean the coffee tastes bad? This article starts from the definition of coffee liquor color, analyzes how roast level and concentration affect the hue, and then reveals the true cause of the murky sensation—the release of insoluble substances and the condensation of soluble compounds as temperature changes. Through examples using the flannel filter, AeroPress, and other equipment, it shows that cloudiness does not equal poor flavor; sometimes it instead brings a richer mouthfeel and sweetness. Front Street Coffee reminds us: judging a cup of coffee should not be based on appearance alone. [more…]

Brewing a pour-over coffee that smells of floral and fruity notes, yet tastes muddled and indistinct in the mouth, with no specific flavors you can name—this is a situation many coffee enthusiasts have encountered. The problem may not be that your technique isn't skilled enough; it could be that something has gone off in the concentration, agitation, bean resting, or water quality.

Understanding this school will change how you think about what "coffee should [more…]
